Brief Summary
Transfusion reactions are defined as harms occurring during or after blood transfusion, with new heart/lung stress (eg. troubled breathing) regarded as cardiorespiratory transfusion reactions (CRTRs). CRTRs are among the most important, as the leading cause of transfusion-related harm and death. Though there are distinct classifications for these events, real life cases often don't fall neatly into a given category, with outliers regarded as "transfusion associated dyspnea (TAD)". It is unknown what TAD is -- whether it has a unique root cause, is a milder version of other known CRTRs, or is a blend of events. The purpose of this study is to better understand TAD and CRTRs by profiling them through a detailed medical history and more intensive laboratory assessment. This review of CRTRs may improve the quality/validity of final conclusions reported in the health record and to hemovigilance bodies, and uncover the nature of TAD and/or minimize CRTRs defaulting to the TAD category. Our enhanced understanding will advance diagnostic, treatment, and prevention efforts.

Outcome Measures
Primary Outcomes (1)
CERTAINTY
Improve certainty in final cardiorespiratory transfusion reaction event classifications (by reduction in the number of cases otherwise achieving no better than "possible" provisional conclusions), from the expected base ambiguity rate of 60%, down to 30%.

PATHOGENESIS FOOTPRINTING

Study Arms (2)
Cases: CRTR (cardiorespiratory transfusion reaction)
Respiratory/cardiovascular disturbances after transfusion (\>/=2 of respiratory distress, pulmonary edema, cardiovascular system changes, fluid shifts, cardiac strain indicators), with or without accompanying (or pre-existing) fever
Controls: HRFTR (high risk febrile transfusion reactions)
Post-transfusion fevers requiring laboratory investigation (Tmax\>/=39C, or lesser deflections if accompanied by chills/rigors), without respiratory features (hypoxia or dyspnea)
Interventions
profile dimensions: * hemolytic * allergic * cardiorenal * inflammatory * leukoagglutinating * exploratory bioarchive
Eligibility Criteria
Adult patients at 4 university-affiliated teaching hospitals who have received a blood transfusion, and experienced a suspected acute transfusion reaction
You may qualify if:
- Age ≥ 18 years
- Transfusion of blood products (components or derivatives) with an available pre-transfusion group \& screen specimen
- Referred to the blood transfusion laboratory for review of a suspected acute transfusion reaction (occurring within 24 hours of completing transfusion), and either exhibiting a cardiorespiratory disturbance (CRTR: cases) or a high-risk febrile disturbance (HRFTR: controls)
You may not qualify if:
- Pregnant females
- Massive hemorrhage entailing \>20 implicated products in the 24h period before the acute transfusion reaction's onset
- Previous enrolment in the same designation (ie- an individual with RTR will not re-enroll if having another RTR, but may re-enrol if having FTR)
- Expected to discharge home or die sooner than specimen acquisition
- Withdrawal of consent at any time
